GH3 is my first foray into music gaming. Never played DDR, or any of the arcade MTV music games or anything previous from GH. So a few weeks ago I got GH3 for the PS3. I played through it on easy without much trouble at all. I tried it on medium and that fourth fret kills me. I've been using practice mode and I still can't get the hang of that fourth fret. Were the previous entries so difficult?
